Clermont-Ferrand (France), 24 September 2026 (7:45 a.m. CEST). Carbios ( Euronext Growth Paris: ALCRB) today reports its first-half 2026 financial results, as approved by the Board of Directors on September 23, 2026, and provides an update on its strategic priorities.

Benoît GRENOT, CEO of Carbios, commented: “The results for the first half of 2026 reflect the benefits of the financial discipline implemented since more than a year ago. In parallel, we have reached key milestones in the financing of the Longlaville plant, notably through credit committee approvals from several banking partners and continued progress in securing pre-sales commitments. Looking ahead, our roadmap is clear: finalize this financing and resume construction of the Longlaville plant, further advance our strategic partnership with Wankai, and accelerate the commercialization of our technology, while maintaining rigorous management of our resources.”

1. Financial results

During the first half of 2026, Carbios continued to execute its cost-control plan launched more than a year ago. Operating expenses decreased by €3.4 million, representing a 19% reduction compared with the first half of 2025. All expenditures were reviewed and optimized to ensure that the Group’s resources remain focused on its strategic priorities.

For the six months ended June 30, 2026, operating loss amounted to €11.8 million, improving by
€3.9 million compared with the first half of 2025.

Net loss came to €9.4 million, compared with €11.9 million in the first half of 2025, reflecting an improvement of €2.5 million.

Carbios SA's net cash consumption was limited to €4.2 million during the first half of 2026, compared with €33.4 million during the same period in 2025, reflecting the impact of the cost-reduction measures and investment cuts implemented:

• Cash consumption during the period was reduced by €8.3 million in operating activities and by nearly €14 million in investing activities compared with the first half of 2025.
• In addition, Carbios SA received a partial repayment of €8 million on the shareholder loan from its subsidiary Carbios 54.

At Group level, cash consumption amounted to €11 million, compared with €18 million in the same period of the previous year. This financial discipline contributed to maintaining a solid cash position of €48 million as of June 30, 2026, enabling Carbios to cover its operating expenses beyond the Next 12 months.

For the second half of 2026, Carbios intends to continue its cost-control efforts while maintaining the resources required to execute its strategic priorities.

2. Update on the financing of the Longlaville plant project

Over recent months, Carbios has achieved several important milestones in the financing of its Longlaville plant project.

These key developments include:

• the completion of independent reviews covering the project's technical, economic, environmental and legal aspects, which confirm both its economic viability and the relevance of its location in France;
• the approval of the credit committees of a majority of the project’s lenders;
• a commercial agreement currently being finalized with a major player in the beverage industry, which is expected to increase the plant’s pre-sales level to 60% of its nominal capacity; and
• the validation of the "fiber-to-fiber" biorecycling process, broadening the addressable customer base for the Longlaville plant.

As of today, due diligence activities conducted by export credit agencies¹ and equity partners remain underway. The implementation of the financing is progressing through a necessarily extensive process, reflecting the innovative nature of this large-scale project.

3. Strategic partnership with Wankai

Since the beginning of 2026, the Company has initiated the operational implementation of the strategic partnership signed with Wankai New Materials on December 2, 2025, notably through the establishment of the Kaibio Biotechnology Co. Ltd joint venture, which will be responsible for constructing the licensed industrial facility, and through qualification tests that confirmed the compatibility of locally available feedstocks and waste streams with the Carbios process.

4. Licensing for the Packaging and Textiles markets

During the first half of the year, Carbios further strengthened the technological maturity of its PET biorecycling solution by validating its application to the treatment of complex textile waste². This milestone enables the Company to expand its licensing offering to the global textile market, in addition to packaging. In this context, the Company is pursuing discussions internationally with a view to granting additional licenses and accelerating the commercial deployment of its technology.

5. Changes in Governance

On May 18, 2026³, the Company announced the appointment of Benoît Grenot, then Deputy Chief Executive Officer, as Chief Executive Officer, effective June 1, 2026, succeeding Vincent Kamel.

On July 30, 2026, the Board of Directors appointed Samir Karoum as an independent director by co-optation, replacing Karine Auclair who had resigned, for the remainder of her term of office. The ratification of this appointment will be submitted for approval at the Company’s Next General Meeting.

6. Availability of the 2026 half-year financial report

The 2026 half-year financial report will be made available on Carbios’ website no later than September 30, 2026.
